BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hesperaloe plant, botanically known as Hesperaloe parviflora and hereinafter referred to by the name ‘MSWNPered’.

The new Hesperaloe plant is a product of a planned breeding program conducted by the Inventor in Glendale, Ariz. The objective of the breeding program is to develop new freely flowering Hesperaloe plants with unique flower form and color.

The new Hesperaloe plant originated from an open-pollination of an unnamed selection of Hesperaloe parviflora, not patented, as the female, or seed, parent with an unknown selection of Hesperaloe parviflora, as the male, or pollen, parent. The new Hesperaloe plant was discovered and selected by the Inventor on Apr. 1, 2007 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Glendale, Ariz.

Asexual reproduction of the new Hesperaloe plant by tissue culture since Apr. 10, 2010, in a controlled greenhouse environment in Waseca, Minn., has shown that the unique features of this new Hesperaloe plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Hesperaloe have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘MSWNPered’. These characteristics in combination distinguish ‘MSWNPered’ as a new and distinct Hesperaloe plant:

-   -   1. Relatively compact plant habit.     -   2. Vigorous growth habit.     -   3. Upright purplish red-colored peduncles.     -   4. Campanulate bright red-colored flowers.     -   5. Good garden performance.

Plants of the new Hesperaloe can be compared to plants of the female parent selection. Plants of the new Hesperaloe differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Hesperaloe are more compact than plants of         the female parent selection.     -   2. Flowers of plants of the new Hesperaloe are bright red in         color whereas flowers of plants of the female parent selection         are yellow to salmon or coral in color.

Plants of the new Hesperaloe can be compared to plants of the Hesperaloe parviflora ‘MSWNPerma’, disclosed in a U.S. Plant patent application filed concurrently. Plants of the new Hesperaloe differ from plants of ‘MSWNPerma’ primarily in flower color as plants of ‘MSWNPerma’ produce flowers that are brownish red to dark purple in color.

Plants of the new Hesperaloe can also be compared to plants of Hesperaloe funifera×Hesperaloe parviflora ‘Perfu’, disclosed in U.S. Plant Pat. No. 21,728. Plants of the new Hesperaloe differ primarily from plants of ‘Perfu’ in flower color as plants of ‘Perfu’ have pink-colored flowers. Additionally, plants of the new Hesperaloe are more compact than plants of ‘Perfu’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Hesperaloe plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Hesperaloe plant.

The photograph at the top of the sheet is a side perspective view of a typical plant of ‘MSWNPered’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical inflorescence of ‘MSWNPered’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants of the new Hesperaloe grown during the spring in one-gallon containers in an outdoor nursery in Glendale, Ariz. and under cultural practices and conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 30° C. to 35° C. and night temperatures ranged from 16° C. to 21° C. Plants were three years old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
